Piercing Shots Issue

Hello fellow hunters.
Playing MM in PvP, I constantly find my pet cc (lullaby/monkey blind etc) broken by the passive Piercing Shots. While not much of an issue in arena since targets are usually different, this poses a problem for me in 1v1 situations. I do use the Glyph of Solace which helps for scatter but I was wondering if breaking pet cc by Piercing Shots is a bug or the intended way.

I didn't play in this patch on retail so I have no first hand experience. Also, the info I got from searching on google was outdated i.e from Cata or before and hence not of use. xD

That's intended. Play BM if you don't want to deal with DOTs on your target.
